A J.P. Morgan Chase & Co. employee charged the bank with discrimination Thursday, saying it denies fathers paid parental leave on the same terms as mothers.

J.P. Morgan offers fathers 16 weeks of paid leave after a child’s birth if they will be the baby’s primary caregiver during that time. Non-primary caregivers receive two weeks of paid parental leave. Biological mothers and other primary caregivers get 16 weeks.
